8 further fields the checker looks for are not published by Crankbrothers, so we leave them blank rather than estimate them, and those 8 checks stay silent on this rear wheel. They are rotor mount, internal width, maximum tire, maximum tire mm, maximum tire basis, minimum tire, e approved and maximum system weight. Each is recorded as “not stated by the maker (not checked)”.
